The Atlantic hurricane season should be slightly slower than initially forecast, Phil Klotzbach and William Gray said in an updated forecast Friday.

The two Colorado State University climatologists now call for eight hurricanes, including three major ones to emerge this season. In June, they forecast nine hurricanes, four major, with sustained winds greater than 110 mph.

They also put the probability of at least one major hurricane striking the U.S. coastline at 64 percent, down from 72 percent in their earlier outlook.

They put the odds of a major system hitting the U.S. East Coast, including the Florida peninsula, at 40 percent, down from an earlier 48 percent.

They continue to predict a total of 18 named storms will develop over the entire season. That would amount to 14 more over the remainder of the season, as four already have formed.

Because waters in the eastern Atlantic near Africa have cooled somewhat, Klotzbach and Gray say some systems could be hampered.

Still, if their predictions hold, it would be a busier than normal year. On average, 12 named storms, including six hurricanes, three major, develop per season.

Put another way, this year's activity should be about 150 percent of the average season. By comparison, 2012 saw 131 percent of the average season - with 19 named storms, including 10 hurricanes.

They expect above normal activity mainly because El Niño, the atmospheric pattern that inhibits storm formation, is unlikely to develop this year.
